Guidance on the Use of Automated Flagger Assistance Devices

This guideline outlines the use of Automated Flagging Assistance Devices (AFAD), mechanically operated temporary traffic control devices used to assist flaggers, by various DOTs and provides information to practitioners on scenarios for determining when to use AFADs; selecting an AFAD, which may include determining the cost/benefit of using such devices; addressing safety concerns or limitations; and making the necessary adjustments when using AFADs.   AFADs may be an appropriate alternative that can potentially increase the safety of flaggers by removing them from the direct flow of traffic, especially when there is no viable escape route for a standard flagger position during operations.   Within the guideline, a table summarizing 11 State standards on the use of AFADs may assist other DOTs in developing their own policy during maintenance and construction activities.   The guideline determines that the overall assessment of AFADs from workers and drivers is positive, and the use of these devices is recommended.
